APPARATUS FOR'CUTTING GROOVE-S IN CARD-BOARD, 80c.

SPECIFICATION forming part of Letters Patent No. 362,180, dated May 3, 1887 Application filed November I3, 1896. Serial No. 218,745. (No model.) Iatented'in Belgium October15,188f i, No. 74,850, and in France October 15,

To all whom it may concern: Be it knownthat I, Tnconoa Runes, a subect of the Emperor of Russia, residing at the cityof Dresden,in the Kingdom of Saxony, 5- Empire of Germany, have invented certain new and useful Improvements in Apparatus for Qutting Grooves in Card-Board and other Similar Materials, of which the following is a specification.

lhe object of my invention is to provide a pew and improved machine for cutting grooves in card-board or like material for the purpose of facilitating the bending of the said cardboard for the manufacture of boxes, &c. The invention consists in the'combination of two rollers, of a grooved cutter located be tween them, the rollers and cutters being held by suitable supports above a roller which carries the card-board, as will be fullydescribed and set forth hereinafter, and finally pointed out in the claims. In the accompanying drawings, Figure l is a front view of my improved apparatus for cutting grooves in card-board,.parts of the roller being broken away and shown in see- I tion. Fig. 2 is a crosssectional view of Fig. i 1. Figs. 3 and 4 are detail cross-sectional views of the cutter. Fig.5 is a detail side view of a modification of the roller. .Similar letters of reference indicate corresponding parts. r The rail or bar e-is provided in each face with a longitudinal dovetailed groove, e, in which the dovetailed ends of,screw-bolts m are mounted to slide, said screw-bolts being passed through slots in arms d and a. Two slotted arms, n,,are arranged side by side on the same side of the rail or bar 0. Outhe lower end of each arm a a roller, b, is pivoted, said rollers 40 being adjacent to each other. On that side of the rail or bar 0 opposite the one provided with the arms a the slotted arm (1 is located, onthe lower end of which a grooved cutterblade, 0, is held, the point of which is between 5 the two rollers b b. Said cutter is grooved or made hollow, and may be semicircular in cross-section, as indicated in Fig. 1, or it may be made V-shaped, as shown in Fig. 3,.or U- shaped, as shown in Fig. 4. The distance between the two rollers b b is equal to the width and of a cardboard-carrying 188G, Nor 176,040.

of the end of the cutter. The top of the cutter is-beveled inward and downward toward the point, and thenbeveled downward and back in the inverse direction, as shown in Fig.-, 2, so that the upper parts of the cutting edge ofthe cutter will first enter the paper or card-v A r board and the'bottom parts later, the upperparts of the cuttingedge thus cutting in advance of the lower parts. The card-board rests upon the roller a directly below therollcrs b and cutter c, and when revolved in the direction of the arrow, Fig. 2, carries the card board and-cuts the desired groove.

The arms a, carrying the rollers b b, and the arm (1, carrying the cutter a, can be adjusted higher or lower, according to the thickness of the-card-board, ahd can likewise be shifted, lengthwise on the roll 6. In case the grooves have to be cut in'quite soft card-board the rollers b are provided along the edge with a cutting flange or projection, bf which cuts into the card-boarda short distance and the cutter then completes the groove.

I hereby disclaim in this application the subject-matter covered by my application No. 202,832, filed May 21, 1886, consisting of a pair of knife-holders pivoted on the bar to swing toward and from each other in a plane parallel to that of the bar in the axis on which the kni fe-holders and circular cutters are mounted, and. of a gage having its point adjacent to the edges of the circular cutters.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.-

1. In an apparatus for cutting grooves in card-board and like material, the combination, with the rail (2, of the arms held on the same, rollers held on the lower ends of the arms, and a cutter held 'onan additional arm, the point of the cuttcr being between the two rollers, roller below the above'mentioncd rollers,- and the cutter between them, substantially as shown and described. r

2. The combination,

with a rail, of adjustable arms on the same, two rollers held on the arms, a knife held on an additional arm and having its point located between the rollers, the top of said knife being beveled downward and inward to within a short distance from the bottom of the cutter and then beveled in the the rail, the point of which is between the two reverse direction to the bottom edge of the rollers, and a cardboard-carrying roller becutter, and a cardboard-carrying roller below the rollers and cutter, substantially as I 5 low the above-mentioned roller, and cutter shown and described. 7
